[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1-5 An ultrasonic tube protection device includes an ultrasonic tube body 1. The ultrasonic tube body 1 includes an upper tube structure 2 and a bottom tube structure 3 connected to each other. The bottom of the upper tube structure 2 is provided with an upper connector structure 4 that is sealed and connected to the bottom tube structure 3. The top of the bottom tube structure 3 is provided with a lower connector structure 5 that cooperates with the upper connector structure 4.

[0024] The upper connector structure 4 includes a second internal connecting tube 8 and an external insert tube 12. The second internal connecting tube 8 has a second connecting thread 9 on its outer side. The lower connector structure 5 includes a first internal connecting tube 6 and an external protective tube 10. The first internal connecting tube 6 has a first connecting thread 7 that mates with the second connecting thread 9. A slot 11 for inserting the external insert tube 12 is provided between the first internal connecting tube 6 and the external protective tube 10. A first sealing ring 15 is connected to the bottom of the slot 11. That is, during connection, the second internal connecting tube 8 is inserted into the first internal connecting tube 6. The first connecting thread 7 and the second connecting thread 9 can ensure the threaded connection between the upper connector structure 4 and the lower connector structure 5 by rotation. At the same time as the threaded connection, the external insert tube 12 will be inserted into the annular slot 11. As the thread rotates and descends, the bottom of the external insert tube 12 can be pressed against the first sealing ring 15, thereby ensuring both the protection of the external protective tube 10 and the sealing operation.

[0025] The upper connector structure 4 is connected to the top of the outer side of the outer tube 12 with a second sealing ring 16. The second sealing ring 16 is set to match the top of the outer protective tube 10. That is, because the upper connector structure 4 and the lower connector structure 5 need to be connected, the outer diameter of the upper connector structure 4 is the same as the outer diameter of the outer protective tube 10, while the outer diameter of the outer tube 12 is smaller than the outer diameter of the outer protective tube 10. As a result, the upper connector structure 4 protrudes a part from the top of the outer side of the outer tube 12. The second sealing ring 16 is set in this part. When the upper connector structure 4 and the lower connector structure 5 are connected, the top of the outer protective tube 10 will press the second sealing ring 16 to perform a further sealing operation.

[0026] The external insertion tube 12 is provided with multiple annular groove structures 13, and a third sealing ring 14 is sleeved inside the annular groove structure 13. That is, by providing a third sealing ring 14 on the outside of the external insertion tube 12, the sealing effect can be further guaranteed. The first sealing ring 15, the second sealing ring 16 and the third sealing ring 14 are all made of natural rubber.

[0027] The upper tube structure 2, the bottom tube structure 3, the upper connector structure 4, and the lower connector structure 5 all have through holes 17 inside. Multiple reinforcing rods 18 are welded inside the through holes 17 in the upper tube structure 2 and the bottom tube structure 3. The reinforcing rods 18 can ensure the strength of the upper tube structure 2 and the bottom tube structure 3, prevent excessive deformation in the event of a collision, and provide protective operation. If the upper tube structure 2 and the bottom tube structure 3 are long, due to welding difficulties, it is possible to choose not to install reinforcing rods 18 or to weld and fix them only at both ends.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
